Season 8 Case 12

History: abdominal pain.   Can you find the abnormality and etiology for abnormality?

Answer: Pancreatitis with peripancreatic fluid collection and pseudoaneurysm formation 

No prior or MRI. Fluid collection ? walled off pancreatic necrosis vs pseudocyst BUT the pseudoaneurysm is the key finding! This is a known complication so look for it!
